DescriptionConstruction and mode of operation
Applications
3TM vacuum contactors are suitable for operational switching of AC circuits of any kind, such as:
• Three-phase motors for reversing, inversing or direct duty (utilization category AC-1 to AC-4)
• Transformers• Capacitors, also back-to-back• Reactors• Resistive consumers.
They are used in conveying and elevator systems, pumping stations, air conditioning systems, as well as in systems for reactive power compensation, on ships, in wind power plants, in open-cast mining, in earthquake zones and in rail-way operation, and can therefore be found in almost every industrial sector.
Switching medium
3TM vacuum contactors make use of vacuum switching technology, which has been proven and fully developed for more than 40 years. Siemens vacuum interrupters operate constantly and reliably throughout their entire service life – without any maintenance.
Design and function
3TM vacuum contactors consist of:
• A high-voltage part, with vacuum interrupters, customer connections and position indicator
• A low-voltage part, with magnetic actuator and control electronics
• Auxiliary switches• Optionally, a closing latch as well as a manual latch release
(emergency off), and a shunt release.
The high-voltage part contains individual, independent pole shells, which can take up the corresponding vacuum inter-rupters. In this way, various pole-center distances are possible. The vacuum interrupters are operated by a common magnetic actuator, which is characterized by a very low holding power in continuous operation. The auxiliary switches are located at the side of the operating mechanism and are freely accessible from the outside. A mechanical closing latch and corresponding latch release modules can be ordered separately. Remote tripping takes place via an electro-magnetic shunt release. The manual mechanic latch release (emergency off) is available for various operating directions.

DescriptionConstruction and mode of operation
Function and mode of operation
The drive lever (3) with the pivot point in A is designed as an angle lever. It represents the kinematic connection between the magnetic actuator and the vacuum interrupters. In case of non-excited magnet, the return springs keep the drive lever in “OPEN” position.
Thus, the drive lever (3) is in its upper position via the bear-ing (4) of the guide nut (5). In this way, the contacts of the vacuum interrupter (8) are separated from each other, and thus kept in “OPEN” position.
For closing, the magnet system (7) is excited. The magnet armature (6) attached to the drive lever (3) is thus attracted against the force of the two return springs. This releases the vacuum interrupter (8), so that the external air pressure can press the moving contact towards the fixed contact.
The drive lever (3) compresses the contact pressure springs (9), thus generating an additional contact force.
The distance between the bearing (4) and the guide nut (5) in “CLOSED” position is a measure for the wear within the vacuum interrupter.
3TM vacuum contactors can be used for cable or bar connec-tions.
The base plate (17) serves for installation without distortion through the four bolting holes.
Control supply voltage, wide-area coils
3TM vacuum contactors can be optionally operated with DC or AC. The control supply voltage should correspond to the data on the rating plate.
Customer-side modifications are possible considering the standards provided in the operating instructions.
Safety shutdown of the magnetic actuator in case of deviation from the normal closing time
3TM vacuum contactors feature a safety shutdown to protect the magnet coils against non-conforming thermal overload during closing. Within certain limits, impermissible and non-conforming delays in the closing process are thus detected and the devices are protected from damage.
Intermittent periodic duty and rapid operation
3TM vacuum contactors are able to perform fast switching frequencies for a short time.
In case of switching under high current load, longer dead times have to be kept. In this case, please contact your re-sponsible sales partner.

DescriptionConstruction and mode of operation
Mechanical closing latch (optionally)
When the 3TM vacuum contactor is closed, the mechanical closing latch (18) is activated. After reaching the latching position, there is an automatic changeover to no-load hold-ing operation. Opening takes place via:
• Electromagnetic latch release (remote tripping via the electromagnetic shunt release) (19), or
• Manual mechanical latch release (20).
When the vacuum contactors are retrofitted (selection B at the 10th position of the order number) with a closing latch or latch release, the following modules must be ordered and installed later:
• Mechanical closing latch with shunt release (19)• Latch release mechanism to be operated manually with
push or pull rod.
Closing and opening delay
3TM vacuum contactors feature a short closing and opening time. (See page 27).
They can also be configured with an additional closing and opening delay for selective operation with other contactors or fuses. Both delays are independent of each other and add to the closing and opening time.
Mounting position
3TM vacuum contactors can be mounted in vertical and horizontal position:
• As fixed-mounted design• Mounted on a withdrawable part or a truck.
Site altitude
3TM vacuum contactors can be used for various site altitudes.
As a standard, 3TM vacuum contactors can be used from –1250 m to +2000 m above sea level.
For higher site altitudes, a configuration is offered from 2000 m to 5000 m.
Severe conditions
For very heavy mechanical stress such as earthquakes or extraordinary shock and swinging loads, a special configura-tion is offered.
*) Observe the distance to high voltage and to earthed components!

DescriptionAmbient conditions, dielectric strength, short-time withstand current and rated operational current
Ambient conditions
3TM vacuum contactors are suitable for operational use in the following climatic classes according to IEC 60721:
Climatic ambient conditions: Class 3K4 1), Class 3K8H 2) Biological ambient conditions: Class 3B1 Mechanical ambient conditions: Class 3M3 Chemically active substances: Class 3C2 3) Mechanically active substances: Class 3S2 4)
1) Maximum of 24-hour mean: +70 °C2) Up to –40 °C3) Without appearance of saline fog and simultaneous condensation4) Restriction: Clean insulation parts
Dielectric strength
The dielectric strength of air insulation decreases with increasing altitude due to low air density. According to IEC 62271-106, the values of the rated lightning impulse withstand voltage and the rated short-duration power- frequency withstand voltage specified for 3TM vacuum contactors apply to a site altitude of 1000 m above sea level. For an altitude above 1000 m, the insulation level must be corrected.
To select the devices, the following applies:
U ≥ U0 x Ka
Ka = e m x (H – 1000)/8150
U Rated withstand voltage under reference atmosphereU0 Rated withstand voltage requested for the place of installationKa Altitude correction factor according to the opposite diagram
Example:
For a requested rated lightning impulse withstand voltage of 75 kV at an altitude of 2500 m, an insulation level of 90 kV under standard reference atmosphere is required as a mini-mum:
90 kV ≥ 75 kV x e1 x (2500 – 1000)/8150 ≈ 75 kV x 1.2
Short-time withstand current
The short-time withstand current is the r.m.s. value of the current that a 3TM vacuum contactor in closed position can carry for a certain time until a short-circuit protection device has responded.
Rated operational currents depending on ambient air temperature
The rated operational currents stated in the catalog are valid for an ambient air temperature of + 40 °C. Lower or higher ambient air temperatures result in different values (see diagram).

DescriptionSwitching duties
Utilization categories
According to IEC 62271-106, vacuum contactors are divided into different utilization categories. The opposite table shows typical applications in accordance with the respective utiliza-tion category.
Switching of motors
3TM vacuum contactors are especially suitable for frequent operation of motors. As the chopping currents of the contac-tors are ≤ 3 A, no impermissibly high overvoltages are produced when accelerated motors are switched during normal operation. However, when high-voltage motors with starting currents of ≤ 600 A are stopped during start-up, switching overvoltages may arise. The magnitude of these overvoltages can be reduced to harmless values by means of special surge limiters.
Switching of transformers
When inductive currents are interrupted, current chopping can produce overvoltages at the contact gap. As the chop-ping current of the Siemens vacuum contactor is less than 3 A, no dangerous overvoltages are produced when the un-loaded transformer is switched off.
Surge protection via limiters
Overvoltages can arise as a consequence of multiple restrikes or by virtual current chopping, e.g. when motors are switched in braked condition or during start-up. Motors with a starting current ≤ 600 A are endangered. Safe protection against overvoltages is ensured by surge limiters. These can be arranged in parallel to the cable sealing ends, preferably in the cable compartment.
Switching of capacitors
3TM vacuum contactors can interrupt capacitive currents up to 315 A up to the rated voltage of 12 kV without restrikes, and thus without overvoltages.
Short-circuit protection
3TM vacuum contactors are not designed to switch short-circuit currents. Therefore, a short-circuit protection must be provided. The best protection is provided by HV HRC fuses or circuit-breakers.
Utilization categories Typical applications
AC-1 Non-inductive or slightlyinductive loads,resistance furnaces
AC-2 Slip-ring motors:Starting, switching off
AC-3 Squirrel-cage motors:Starting, switching offduring running
AC-4 Squirrel-cage motors:Starting, plugging 1), reversing 1), inching 2)
1) By plugging or reversing is understood stopping or reversing the motor rapidly by reversing motor primary connections while the motor is running
2) By inching is understood energizing a motor once or repeatedly for short periods to obtain small movements of the driven mechanism

DescriptionSwitching duties
Short-circuit protection via HV HRC fuses
At high short-circuit currents, HV HRC fuses have a current-limiting effect, i.e. the fuse limits the short-circuit current to the let-through current. When selecting the fuses, the type of consumer must be observed, e.g. motor, transformer, capacitor.
The opposite diagram shows an example for the coordination of an HV HRC fuse with a time-overcurrent protection.
Coordinating the components of the motor circuit
• The time-current characteristic must be located on the right of the motor starting current (point A).• The rated current of the HV HRC fuse-link must exceed the normal current of the motor.• The current corresponding to the intersection B of the HV HRC fuse-link characteristic and the characteristic of the time-overcurrent protection must be higher than the mini-mum breaking current of the HV HRC fuse-link.• If this is not feasible, it must be ensured that overload currents that are smaller than the minimum breaking current of the HV HRC fuse-link are interrupted by the switching device via the striker. This prevents thermal overloading of the HV HRC fuse-link, which would otherwise be destroyed.• The selected HV HRC fuse-link limits the sustained sym-metrical short-circuit current IK to the let-through current ID, shown in the diagram for the current-limiting characteristics (ID as a function of IK for HV HRC fuse-links with different rated currents). The maximum tested let-through current is ID = 46 kA.
Requirements
• It must be ensured that the vacuum contactor cannot open until the fuse has interrupted the overload current. If necessary, the contactor opening time must be extended. 3TM vacuum contactors feature the corresponding setting facility. This does not apply if a mechanical closing latch is used. In this case, the time delay between tripping of the fuse and the latch release signal must be considered by the operator.• Due to the arising motor starting current, the instant when the motor starts represents the maximum stress for the HV HRC fuse. This stress must neither operate nor predamage the fuse.
Other factors of influence on the stress of the HV HRC fuses are the starting time and the starting frequency of the mo-tors.

2 Characteristic of the time-overcurrent protection

14 3TM Vacuum Contactors · Siemens HG 11.23 · 2019
DescriptionSwitching duties, standards and type approval
Short-circuit protection for “class E2 controllers” according to UL 347 / CSA C22.2
For using 3TM vacuum contactors as “class E2 controllers”, fuses are specified for short-circuit protection. If two fuse-links are connected in parallel, the symmetrical short- circuit current determined has to be divided by two, and the associated let-through current for one fuse-link must be stated. This value must then be multiplied by two in order to obtain the total let-through current, which must not exceed the permissible value for the vacuum contactor. The parallel connection should ensure that the resistance values in the two branches are almost the same. When the fuses operate, the vacuum contactor must be switched off. A suitable de-vice, actuated by the striker of the HV HRC fuse-link, has to be provided.
Short-circuit protection by circuit-breakers
Consumers for which no suitable fuses are available can also be protected by circuit-breakers. During the longer break time of the circuit-breakers (as a rule, 35 to 60 ms), the symmetrical short-circuit current must not exceed the maxi-mum permissible value.
Overvoltage category
3TM vacuum contactors can be used up to overvoltage category III.
When used in higher categories, surge arresters must be integrated in the control circuits.
Trip-free mechanism
The contacts of the 3TM vacuum contactors are trip-free. In the event of an opening command being given after a closing operation has been initiated, the moving contacts return to the open position and remain there even if the closing command is sustained. This means that the contacts are momentarily in the closed position.
Standards
3TM vacuum contactors correspond to the standards:
• IEC /DIN EN 62271-1 High-voltage switchgear and controlgear – Part 1: Common specifications
• IEC /DIN EN 62271-106 High-voltage switchgear and controlgear – Part 106: Contactors and controllers
• GB /T14808 High voltage alternating current contactors and contactor-based motor-starters
• UL347, 6th edition Medium-Voltage AC Contactors, Controllers, and Control Centers
• CSA C22.2 253-09, Medium-voltage AC contactors, controllers, and control centres
• IEC 61000-4-18, EN 61000-6-2, EN 61000-6-4, EN 55011 Electromagnetic compatibility (EMC)
• DNVGL-CG-0339 Classification and construction standards for ship technology.
Type approval according to German X-ray regulations
The vacuum interrupters fitted in the switching devices are type-approved in accordance with §8 of the X-ray regula-tions (RöV = Röntgenverordnung) of the Federal Republic of Germany as interference radiators, and they meet the requirements for interference radiators according to Annex 2 No. 5 of the latest RöV up to the rated voltage specified in the approval document.
Performance in case of voltage dips or reductions of the control supply voltage Ua
3TM vacuum contactors fulfill the requirements concern-ing voltage dips and reductions with the values requested according to IEC 61000-4-29/08.2000, IEC 61000-4-11.
Mirror contacts
3TM vacuum contactors are equipped with mirror contacts.
Positive opening / Positive driving
The auxiliary switches are mechanically connected with the operating system and are positively moved and driven (posi-tive opening /closing).
Degree of pollution
3TM vacuum contactors fulfill the conditions according to pollution degree 3.
Degree of protection
3TM vacuum contactors fulfill the degree of protection IP43, except for the main circuit and the connections for which the degree of protection IP00 applies.
